The Total 24 Hours of Spa remained under red flag conditions at 08.00 on Sunday morning as heavy rain continued to fall over the Ardennes circuit.
After a week of clear skies and high temperatures at the Belgian venue, bad weather arrived with a vengeance on Saturday afternoon – just in time for the race, which began at 16.30. This necessitated a safety car start, but the track dried out during the early stages and the majority of runners had switched to slick Pirelli tyres by the time the second hour arrived.
The rain returned later in the evening, however, and grew heavier as the night wore on. By the early hours of the morning it had intensified to the point that a red flag was necessary for safety reasons. This was first shown at 06.00, with the field following the safety car into the pits to wait for better conditions.
They remained there at 08.00 on Sunday morning, with no restart expected before 11.30.
